• ​Setting up LRS2 observations.
• ​Entering a temporary target list.
• Systematic study of ACAM properties (plate scale, position angle, photometric zeropoints) using data sets gathered in HET pointing tests.
• Development of LRS2 pointing tools: real-time spatial mapping for observing (target position and PSF) as well as mapping relations between fiber number, IFU spatial position, and ACAM pixel positions for both LRS2-R and LRS2-B.
• Learn software version control system subversion (svn) and use it to archive personal software packages like gstar, lrs2g, ....

(A) scope currently under discussion, (B) underway, (C) done as far as it can progress so far, paused, (D) done to handing-off point, availability to revisit, (E) done, [excludes stuff which is too minor]

---

TOPIC: control of observational phase-blocking/filling to suit several contrasting science driven modes (D)

TOPIC: statistics of HET transparency/skybrightness/IQ data, broken down to calendrical month level; sky brightness modeling in conjunction with this (C)

TOPIC: (for agenda) scheduling optimization algorithm endowed with freedom to lead or lag the naive best time (target slot) approach out to some effciency criterion ; used method of mock queues scheduled according to some contrasting approaches; in short, contrasting with HETmarkI where nonzero lead/lag was not explicit in optimizing scheduling, a Priority-Trumps-All method (taking in many hours as a whole) does well now (not racking up time gapping interims), although it is good to have a backup On-the-Fly ("what's the best target I can do right now and onward from that choice?") schedule re-constituting trigger ready for really disrupted situations (C)

TOPIC: work out decs for which the elevation 55 sidereal crossings proceed at the n x 45 deg d(alt in deg)/d(az in great circle deg) directions, and the start time corrections needed to plug into these tracks from start to finish, working only with htopx ; purpose was to get precisely timed and filled box-pointing exercises for tests instead of hit-and-miss outcomes (E)

TOPIC: photometry from guiders, goals of intra-night70 zeropoint control reliant on catalogued stars, and estimated magnitudes for uncatalogued stars reliant on intra-night zeropoint control ; HET acam Bgri zeropoints, color-equations obtained from 13 stars 20160321 (C)

TOPIC: local healthcheck versions for lrs2 and virus images in respect of gauging twi cmp flt zro and object images quickly in some quantitative ways twi, cmp, flt, zro ; these tools are checked out and in place (E)

TOPIC: automated acam IQ tools ; these yield imexam-a quality fwhms (beware of moment-based fwhms which covary hugely with object brightness) (E)

TOPIC: nightcam hardware function, software control, software reductions (B) }}}

Create a HETDEX conflict calendar for use by the PIs

Create the beginning and end Trimester reports

NOSS keywords and web pages

Here are a few requested updates for the NOSS keywords:

• Change keyword HRSemMAX to HRSemTMAX
• Add keyword HRSemND (Neutral density filter with either yes/no or 1/0)

Edit the old engineering web pages

Projects that Need to be done but no assignment

• Change PI Target notes so they can be editted
• Rewrite ​https://het.as.utexas.edu/HET/hetweb/calsearch.html to add the new instruments and use the current database.
